activate thermotron from labview

[LG_LabVIEW]

Hi,

I am trying to communicate with Thermotron Chamber(TH8800 Controller) via serial comms, I downloaded Thermotrons VI's but did not get them to work - I receive erros!

Perhaps I have not configured the 8800 controller correctly for receiving serial comms from a PC - can someone please tell me exact steps i must ensure are set on controller to ensure correct operation via serial comms,

Should i only have Serial Comms selected in 8800 computer I/O and must every command sent to chamber end with special delimiting charatcer?

Thanks

May be a day late and a dollar short but i'm using the Thermotron Supplied Themotron SubVI's I will Attach them. I simply modified these files to accomodate any data aquisiton going on as well and restructured the commands into tabs.

Hope it Helps

Sincerly, Billy G. Alexander

Your not as late as me!!!

These subVI's are for a TCP\IP connection what is involved in changing this to a RS232 coonection or is there a completely different set of VI's for this type of interface

Hope you can help

Hey, 

        I think we can re-animate this dead animal.

I Went back an looked through my folders and found the attached Drivers. You will need to move the supplied DLL's into the appropriate location's but that should be an issue

I took a quick look in the library files they use a standard I/O so you can just point it to a Com address for your RS232

Thanks,

In the attached installation instructions, it said to put the .dll into C:\VXIpnp\WinNT\bin, this directory doesnt exist . is it just as simple as creating this directory and putting the .dll file into it?

I am using a USB to Serial connection, with a 3 null RS-232 cable.

I have downloaded the drivers and placed the file in the correct location and mass complied as per instructions.

I have also placed the .dll file into the correct file which I created

Next I am trying to send commands through the visa test panel but I am still receiving a time out error

Have you any ideas were I am going wrong.
